Is it too late now to say he's sorry? Charlie Puth made a disparaging comment toward Justin Bieber in Dallas on Friday, March 11, while performing his song “We Don’t Talk Anymore.” The 24-year-old singer later apologized for his remarks, but deleted the apology shortly afterward.

“F‑‑k you, Justin Bieber!” Puth, 24, shouted in the middle of the performance on Friday, followed by overwhelming cheers from the audience (see the NSFW moment below).

“Hey everyone. I feel like I need to clear something up,” he wrote in the now-deleted tweets. “What I said at the concert last night about Justin was meant to be a joke. However.. The way it was said mid song did not sound like one.”

He continued, “I am a massive @JustinBieber fan and I have nothing but great things to say about him and his music always.”
